Which IT Systems Could Interrupt Your Manufacturing Operations?

Your production equipment may be working perfectly. But what happens when the technology supporting it becomes unavailable?

For manufacturers, operational continuity depends on more than production machinery.

The systems supporting scheduling, inventory management, communication, shipping, and other daily processes can play an important role in keeping work moving.

When those systems experience an outage, the effects may extend beyond the IT department.

Employees could lose access to production schedules. Orders may become difficult to track. Warehouse teams may have trouble processing shipments. Critical information might be temporarily unavailable to the people who need it.

The extent of the disruption depends on how the manufacturer's systems and processes are connected.

That's why manufacturing cybersecurity and IT risk management should begin with a practical question:

Which technology systems does your operation depend on, and what would happen if they stopped working?

Why Technology Dependencies Are Receiving More Attention

Manufacturing technology environments increasingly involve connections between traditional information technology (IT), operational technology (OT), cloud platforms, vendors, and business applications.

IT generally includes systems used to manage information and business operations, such as servers, networks, business software, and employee workstations.

OT includes systems that monitor or control physical processes and equipment.

Although these environments serve different purposes, they may share important operational dependencies.

On September 21, 2026, the National Institute of Standards and Technology (NIST) released an updated public draft of its Guide to Operational Technology Security.

The draft addresses security considerations for OT environments, including asset management, risk governance, monitoring, and the relationship between technology security and business operations.

The document remains a public draft, with comments due November 30, 2026. It should not be interpreted as a new regulatory requirement for all manufacturers.

Additional industry research highlights why organizations are examining these connections.

In its October 2026 State of Critical Infrastructure Cybersecurity research, Palo Alto Networks reported that:

• 68% of surveyed organizations lacked complete, real-time visibility into connected OT assets.
• 74% had not fully integrated IT and OT security operations.
• 42% identified legacy OT equipment that could not be patched as their most significant cybersecurity risk.

The survey included more than 1,600 security leaders across multiple critical infrastructure sectors and countries. These figures are not specific to manufacturing companies alone.

Still, the research reflects a broader challenge: organizations need a clearer understanding of the technology supporting their operations and how security weaknesses or outages could affect those operations.

For manufacturers, the starting point doesn't have to be an entirely new cybersecurity program.

It can begin by identifying the systems the business already relies on.

Five Technology Dependencies Manufacturers Should Understand

1. Production Scheduling and Business Management Systems

Manufacturing operations often rely on business software to coordinate production schedules, inventory, purchasing, and order fulfillment.

These systems may include enterprise resource planning (ERP) software, manufacturing management applications, and other business platforms.

If employees suddenly lose access to those applications, their ability to coordinate work may be affected.

For example, a production team might still have functioning equipment but be unable to retrieve updated work orders or determine which materials are available.

Questions manufacturers should ask:

• Which applications support production planning and scheduling?
• Where are those applications hosted?
• Who is responsible for maintaining them?
• What other systems must be available for employees to use them?
• Is there a documented process for continuing essential work during an outage?

The goal is to understand how a technology disruption could affect production-related decisions and workflows.

2. Network Infrastructure and Connectivity

Networks connect employees, applications, servers, and other technology resources.

Depending on the manufacturer's environment, those connections may also support communication between business systems and equipment-related services.

A network disruption could prevent employees from accessing important applications even when the applications themselves are still functioning.

Manufacturers should understand which network components support critical business processes and which connections require special attention.

Questions manufacturers should ask:

• Which network systems are essential to daily operations?
• Are important connections monitored for availability and performance?
• Are external connections and remote access appropriately secured?
• Who is responsible for responding to network disruptions?
• Have important network dependencies been documented?

For environments where business IT and OT are interconnected, changes to network security should be coordinated with the personnel responsible for production equipment and safety.

Traditional business IT controls should not be applied indiscriminately to industrial control systems without evaluating their operational requirements.

3. Identity and Access Management

Technology systems are only useful when authorized employees can access them.

Manufacturers may rely on centralized identity platforms, business application accounts, remote access services, and shared information repositories.

If an identity service becomes unavailable, employees may have difficulty accessing applications needed for daily operations.

Poorly managed permissions can also create cybersecurity risk.

For example, a former employee may retain access to an application, or a third-party vendor may have permissions that exceed what is necessary.

Questions manufacturers should ask:

• Which applications depend on centralized employee authentication?
• Is multifactor authentication enabled where appropriate?
• Are access permissions regularly reviewed?
• How quickly can employee and vendor access be changed or revoked?
• Are privileged accounts appropriately restricted?

Effective identity management supports both security and operational reliability.

It can help reduce unauthorized access while ensuring employees have the permissions needed to perform their responsibilities.

4. Data Storage, Backup, and Recovery

Manufacturing companies depend on information such as production schedules, purchasing records, customer orders, inventory data, engineering documents, and financial records.

If that information becomes unavailable or corrupted, employees may be unable to complete important tasks.

Backup and recovery planning should account for both data protection and operational priorities.

Having backups does not necessarily mean every important system can be restored within the time the business requires.

Questions manufacturers should ask:

• Which data and business systems are essential to operations?
• Are those systems covered by appropriate backup arrangements?
• Have restoration procedures been tested?
• Does leadership understand how long recovery may take?
• Which systems should be restored first following an outage?

A manufacturing business may determine that restoring its ERP system is a higher immediate priority than restoring a less critical administrative application.

Another manufacturer may have different priorities based on its operations.

Those decisions should be made intentionally and documented before a disruption occurs.

5. Vendors and Third-Party Technology Support

Many manufacturing businesses rely on external technology providers to maintain applications, infrastructure, or specialized systems.

These relationships can provide important expertise, but they also introduce dependencies.

For example, a company might depend on a software vendor to restore access to an essential application.

Another provider might manage network equipment, cloud services, or a specific business system.

Manufacturers should understand which outside organizations are essential to recovery and what responsibilities each provider has.

Questions manufacturers should ask:

• Which vendors support business-critical technology?
• What access do those vendors have?
• Who should be contacted if a critical system becomes unavailable?
• Are responsibilities for troubleshooting and recovery documented?
• What happens if a vendor cannot respond within the time operations require?

Third-party oversight should consider both cybersecurity exposure and operational dependency.

A vendor may have limited access to sensitive information but still provide a service that is essential to maintaining business operations.

How Technology Dependencies Create Cybersecurity Risk

Technology dependencies become particularly important when a cybersecurity incident affects systems that support multiple business processes.

Consider a hypothetical manufacturer whose ERP software depends on a centralized server, employee authentication, network connectivity, and a cloud backup service.

A problem with any one of those supporting components could affect access to the ERP application.

The underlying cause might be a technical failure, a configuration problem, an outage involving a third-party service, or a cybersecurity incident.

The business consequences depend on how essential the ERP system is to operations and whether alternative procedures are available.

Understanding these dependencies helps manufacturers evaluate risk beyond individual devices or applications.

It also helps leadership identify where security controls, maintenance, and recovery planning deserve additional attention.

Why a Technology Inventory Is Only the First Step

An asset inventory helps identify the systems an organization owns and manages.

But knowing that a server or application exists doesn't necessarily explain its operational importance.

A manufacturer may maintain an accurate list of servers, workstations, software, and network devices without clearly documenting which systems support critical business processes.

That's where technology dependency mapping can provide additional value.

Rather than looking at each technology asset independently, the process connects systems to the operations they support.

For example:

These are illustrative examples. Actual technology dependencies and consequences vary by manufacturer.

This information can help identify which systems require heightened attention in cybersecurity risk assessments, maintenance planning, and recovery strategies.

It can also make conversations between IT leadership and operations teams more productive.

What Should Manufacturing Leadership Know About Technology Risk?

Manufacturing executives don't necessarily need to understand every technical configuration in their environment.

They do need sufficient information to evaluate which technology risks could affect business operations.

A useful technology-risk review should help leadership answer:

1. Which business processes depend on specific IT systems?
2. Which systems would create the greatest operational disruption if unavailable?
3. Are important systems appropriately maintained and protected?
4. What known vulnerabilities or configuration issues need attention?
5. Are recovery priorities documented and tested?
6. Who is responsible for addressing identified risks?

These questions connect cybersecurity findings to operational consequences.

They also help leadership make more informed decisions about technology investments.

For example, an aging business server supporting an essential application may deserve greater attention than a newer system used for a less important purpose.

Similarly, a backup weakness affecting a critical application may warrant a higher priority than an issue involving information that can be easily recreated.

The objective is to prioritize based on risk rather than treating every technology issue as equally urgent.

How Manufacturers Can Begin Evaluating Their Technology Dependencies

A manufacturing organization can begin with a focused review of its most important business processes.

Step 1: Identify critical processes

Start with the activities that are essential to maintaining operations, serving customers, and fulfilling orders.

Step 2: Identify supporting IT systems

Determine which applications, servers, networks, identity services, and data repositories support those processes.

Step 3: Evaluate operational consequences

Consider what would happen if each supporting system became unavailable, including the effect on employees, production coordination, and customer commitments.

Step 4: Review existing safeguards

Evaluate relevant access controls, system maintenance, cybersecurity risks, backup arrangements, and documented recovery procedures.

Step 5: Prioritize improvements

Identify which gaps create the greatest potential business impact and establish a practical plan for addressing them.

This approach does not replace a specialized OT security assessment when one is needed.

Instead, it provides manufacturers with a starting point for understanding business IT dependencies and coordinating related security and resilience efforts.

Cybersecurity Planning Should Start With What Keeps Your Business Running

Manufacturing cybersecurity isn't only about protecting individual computers or responding to technical alerts.

It's also about understanding which technology systems support the business and how weaknesses or disruptions could affect operations.

When manufacturers identify critical IT dependencies, they are better positioned to prioritize maintenance, cybersecurity improvements, backup planning, and recovery preparation.

That creates a more practical connection between technology spending and business risk.

Before deciding which security tools or IT upgrades to invest in next, manufacturers should understand which technology systems their operations cannot afford to lose.
